Creating ExtensionClass instances in C
Here's a simple question about the ExtensionClass API: if I write an ExtensionClass, how do I create an instance of it from C code? There's no obvious API function that does this... --amk
Have you tried calling it? That seems to be what python does in order to create instances. Something like: instance = PyObject_CallFunction((PyObject *)extension_class, "formatstring", constructor_args); I think that should also work on normal python classes. BTW, I have my extensionclass C subclassing patch in the collector at: http://classic.zope.org:8080/Collector/1179/view if anyone wants it. I also have an example of its use in the test release of my python bindings for gtk at: ftp://ftp.daa.com.au/pub/james/python/pygtk-0.7.0-unstable-dont-use.tar.gz (I should probably put up a newer snapshot at some point).

After a bit of poking around in Python's .h files, it seems as if PyObject_NEW() works. Hmmm... but does it call the __init__ method? Maybe your solution is the correct one. Jim, any idea? --amk
